Claims

[Scope of utility model registration request]

A transfer electric field is applied to the photoconductor, an endless transparent dielectric belt that contacts the photoconductor at the center of its upper surface, and a transfer paper conveyed on the dielectric belt from the back side of the dielectric belt at the transfer position. In a copying machine equipped with a transfer corona device that provides a transfer corona device, a light-emitting element and a light-receiving element are provided so as to sandwich the upper surface side of the dielectric belt on the downstream side of the transfer position, and the light-emitting element and the light-receiving element are arranged to sandwich the upper surface side of the dielectric belt and receive light for a control toner image pattern transferred onto the dielectric belt. The device reads the information and uses this detection output to control at least one of the photoreceptor charge amount, exposure amount, developing bias, and toner density, and also detects the presence or absence of transfer paper on the dielectric verit at the timing of transfer paper feeding. A control mechanism for a copying machine characterized by detecting a jam.
